I would argue that FB is a threat to their search ads, too, in the long run. And it's not too difficult to foresee some scenarios in which that's true. At least Google seems to think so. (If they just thought FB was a threat to display ads, they probably wouldn't be making social such a huge, life-or-death deal).
